spherical pulse ionization chamber

The AlphaGUARD Portable Radon Monitor with a pulse ionization chamber is put into an adjustable air pressure radon chamber which has a solid radon source,and when changing the inner air pressure,we measure air pressure effect.

闪烁室和电流电离室注入恒量的氡气,改变其内的气压进行放射性计数测量;脉冲电离室的AlphaGUARD便携式氡监测仪则放入一有固体氡源的可调气压的氡室,改变氡室气压对其进行气压效应测试。
